Creating Topic-Specific Maps for Geoscience Classes

Introduction

We can help students understand spatial relationships through the inclusion of specific maps that relate to the lecture, discussion, lab or exercise topics (see for example, Gutierrez et al. (2002)). While the use of state- or national-level geologic or topographic maps in geoscience coursework is quite common, available GIS tools and data provide opportunities to develop site- or topic-specific maps to enhance the experience. Map development tools are available in numerous desktop GIS packages (e.g. ArcView or GRASS) or web-based GIS servers (e.g. www.terraserver.com , http://nationalatlas.gov/ or http://seamless.usgs.gov (more info) ).

Once created, these maps become resources for future course/lab work. They are also an effective way for the instructor to train in GIS techniques.
